It’s been reported in a number of posts, news articles, and even on local television shows that two mysterious giant boxes have appeared in the San Francisco harbor next to Treasure Island and another one just like it is being constructed in the Portland Main harbor. The boxes are roughly four stories tall, 250 feet long, and 70 feet wide. They are made from cargo containers stacked on barges and, according to the reports, everyone is pretty sure the structures belong to Google.
